Thermotech Heating and Cooling | HVAC Services in Kent, WA 98031

For most Kent homes, we recommend checking your filter monthly and replacing it every 1-3 months. Our local environment, with seasonal pollen and occasional dust, can clog filters faster. A clean filter is crucial for maintaining airflow, protecting your system's components like the air handler fan, and keeping your energy bills down.

Common signs of a failing air handler fan in your Kent home include weak airflow from vents, unusual grinding or screeching noises from the indoor unit, the system frequently cycling on and off, or a complete lack of heating or cooling. If you notice these, it's best to call us promptly to prevent further damage to your HVAC system.

Absolutely. A severely clogged filter restricts airflow, causing your system to work much harder. This strain can lead to overheating, frozen coils, and premature failure of critical parts like the air handler motor. Regular filter changes are the simplest and most effective maintenance you can do to avoid unexpected breakdowns and costly repairs.
